Events have a global, system-wide sequence number, which must be handled
atomically, (fetching and incrementing the sequence AND sending the event
to uORB must be atomic). Currently in FLAT mode, only one instance of this
sequence number exists, so it is OK to have it in px4_platform.
However, in PROTECTED mode px4_platform is instantiated both in kernel-
and user spaces, which makes two instances of this sequence number, which
causes problems in the mavlink event handling logic.
When mavlink receives and handles events, it expects that:
- The sequence numbers arrive in order (seq n is followed by n+1 etc)
- It increments by 1
- There is only one instance of the sequence number
In PROTECTED mode this is violated, as the kernel and user sequence
numbers run freely on their own. This patch fixes the issue by moving
the event backend to the kernel and by providing user access to it via
ioctl.
Even if there is some horizontal motion, a passing check should be
accepted as the terrain can be flat. However, the vehicle must not be
moving horizontally to invalidate the consistency as a change in terrain
can make the kinematic check temporarily fail.
A setpoint of type IDLE can be published by Navigator without a valid position,
and should be handled in the auto function in FW_POSCTRL_MODE_AUTO. If it wouldn't be
handled there the controller would switch to mode FW_POSCTRL_MODE_OTHER, in which case
no attitude setpoint is published and the lower controllers would be stuck with the
last published value (incl. thrust).

but this time compared to
2fbb70d9ca94f442de1345221be18ba738cda952
the minimum thrust is ramping to not produce a thrust jump.
The better long term solution will be to always have airmode but
with the effect limited to a magnitude of MPC_MANTHR_MIN.
high rates and (super) expo are necessary for
- acrobatic flying
- fpv
- racing
but they are not useful for:
- a typical vehicle's rate control tuning
- beginners
The defaults that I set in #8036 were put with the assumption Acro mode
is mainly used on racing drones for acrobatic manouvers but instead
users including me use it most of the time to tune any drone.
When tuning the rates are lowered and expo disabled.
My suggested strategy is to make the beginner friendly rates without
expo which are good for tuning the default and document more clearly
how this can be raised for acrobatic flying in documentation and later
on hopefully also directly in the ground station UI
on an Acro mode specific page.

If no altitude setpoint is specified then takeoff to the default
altitude above the current global position, not above Home.
